DESCRIPTION

The present invention relates to a device for recharging known as "power bank" for the recharging of electronic devices via wireless or through electromagnetic induction and, more precisely, to a portable "power bank" which allows the user to recharge electronic devices via electromagnetic induction, and the carrying thereof during the charging while said devices are coupled to said power bank .

The present invention it is particularly directed to the use thereof with a smartwatch.

State of the art

To date are widely known the so-called "power bank" as charging devices to provide electric power to electronic devices while on the move and far from a fixed charging point .

Typically, such power banks are constituted by one or more accumulators accommodated within an enclosure and suitable to be charged through a USB cable from a power source, such as a laptop computer or a wall charger. Once the accumulators are charged, the Power Bank can provide power to any electronic device (i.e., smartphone, smartwatch, tablets, cameras, camcorders, etc.) through for example, a USB connection.

On the other hand, it is more and more present in the market of wearable electronic devices (wearable technology) the so-called "smartwatch". As it is known, a "smartwatch" is a clock that has several additional features to the simple clock function, and typically these additional functions are those which are normally provided in a "smartphone" (last generation mobile phone) . A smartwatch it is in fact a peripheral device that functions as an extension of a smartphone display while the latter is being carried .

Further, such smartwatch in order to function with the totality of functions it must interface with a smartphone carried by the user, and via a Bluetooth connection.

Moreover, there are already many of smartwatch models having different sizes and shapes for what concerns the dial, the straps, power of the battery, etc. and which interface with different operating systems, typically both iOS and Android.

On the other hand, given the nature of the smartwatch device, the same it is charged via magnetic induction (i.e. wireless) . Wireless charging, also known with the technical term "inductive charging", it is a technology recently introduced in many new smartphone and smartwatch and which allows the recharging the terminal device without a direct connection via a cable but via electromagnetic fields generated by a second device, usually a wireless charging base. The base it is connected to the power supply, and provides a surface onto which the device can be placed on the back side thereof. The contact between the base and smartphone (or smartwatch or similar product) leads the energy coming from the wall outlet directly to the battery of the portable electronic device via electromagnetism. In this way and without using any wire connected through the docking station, the smartphone or the smartwatch it is recharged .

A first disadvantage of the presents solution consists of a wireless charging of the device but not on the move. In fact, for the inductive charging the electronic device to be charged must be exclusively placed or resting in contact with the bas, and therefore the same does not allow the user to recharge the device in mobility.

Another disadvantage resides in the fact that most of the charging bases in order to function they must be connected to a power source. In fact, typically the charging bases have to be placed onto a desk or onto a work table and close to said power supply.

On the other hand, the movable "power bank" charging base are known, i.e. charging bases internally equipped with accumulators and which to function do not need to be electrically connected to a power supply network. However, this type of charging base does not allow the user to charge the electronic device in mobility, since it must be put on a surface and the device to be charged must be statically positioned onto the same.

Brief description of the invention

The object of the present invention it is to solve the aforesaid disadvantages by providing a device for charging electronic devices using magnetic induction in mobility, i.e. being able to perform the charging of the electronic device via magnetic induction even if the user is in motion .

Another object of the present invention is to provide a device for charging electronic devices using magnetic induction in mobility that is of reduced sizes such as to be easily carried by a user in a pocket or the like during its use.
